Printed Circuit Board Production

Printed circuit boards require pure water in many processes within their manufacture, including maintaining the level of the plating bath, mixing solutions such as the alkaline post production cleaning solution, and washing to remove unwanted copper from the board.

Due to the nature of the circuit board, the water used throughout its production is required to be deionised. The extremely low electrical conductivity makes it safe to be applied directly to future electrical connections. The lack of conductive ions within the water, and particles removed pre reverse osmosis, give the board a great finish and reduces the risk of having broken tracks and faulty connections.

Treatment Process

1

Particle Removal

Our cartridges offer outstanding absorption of sediment, dirt, sand and scale flakes to prevent filtration systems from blockage and microorganism growth.

2

Chlorine and Organics Removal

Carbon cartridges are a long established choice for the reduction and removal of chlorine, VOCs and heavy metals whilst reducing water hardness.

3

Reverse Osmosis

Pure water (permeate)  is produced during reverse osmosis by applying pressure to force water through a semi permeable membrane, leaving a majority of the present ions and dissolved solids on the other side to drain as waste (concentrate).

4

Post RO Deionisation

Our performance mixed bed resin is specially designed for deionisation directly after reverse osmosis. It holds a 1 : 1.5 ratio of strong acid cations and strong base anions to attract and remove all ions, salts and dissolved solids.

5

Ultraviolet Sterilisation

Our UV Systems produce light radiation at 253.7 nm, the ideal wavelength to kill and inhibit the growth of 99.9% of bacteria and viruses without any by product or requirement of chemical treatment.
